Teachers, I want to ask why I can't find the BTC-USDT perpetual currency I bought 100,000 U yesterday? It doesn't show up on OK, what's going on? I just woke up and saw a text message saying it was forced to close. What does forced closing mean? Teacher #5月市场关键事件 #香港加密货币ETF #以太坊ETF批准预期 #符文协议有前景吗？ #Meme币你看好哪一个？
